On April 10 the U.S. Naval Air Systems Command awarded Northrop Grumman a $3.17 billion contract modification covering ongoing procurement of the E-2D Advanced Hawkeye (AHE) carrier-borne airborne early warning aircraft. The modification raises the previous Lot 7 advance acquisition contract to a multi-year, fixed-price-incentive firm contract that covers the acquisition of 24 AHEs in production lots 7-11, with work expected to be completed by August 2026. Almost $1 billion is being procured from the FY19 budget.
First flying in 2007, the E-2D represents a major overhaul of the Hawkeye concept, fitted with new electronics and communications with an accent on networking, tactical “glass” flight deck, improved Rolls-Royce T56-A-427A engines, and a new radar in the form of the Lockheed Martin APY-9 UHF system with hybrid electronic/mechanical scanning. While the antenna arrays have electronic scanning, the rotodome in which they are housed rotates, as with the earlier Hawkeye radars.
